Embodiment 1

[0045] see Figure 1-Figure 4 , this implementation provides a naked-eye three-dimensional display method based on multi-viewpoint reconstruction, including the following steps:

[0046] Step 1: Firstly, obtain the dense viewpoint images of different angles of the three-dimensional object through the 2D+depth algorithm, and enlarge these viewpoint images by a certain multiple in the horizontal direction.

[0047] Step 2: The display side adopts the method of parallel arrangement of multi-layer screens, and sets the convergent viewpoint in front of the screen. The so-called convergent viewpoint means that there is a light at the position corresponding to each convergent viewpoint and each pixel on the last layer of screen . When the rays of light in different directions pass through the multi-layer display, each ray will form an intersection point with each layer of the screen, and the brightness and color information corresponding to the positions of the multiple intersection...

Abstract

The invention discloses a naked eye three-dimensional display algorithm based on multi-view reconstruction, a plurality of dense view images are obtained, a plurality of layers of screens arranged in parallel are used at a display end, a plurality of convergence view points are arranged in front of the screens, a light ray is arranged at the position, corresponding to each pixel on the last layer of screen, of each convergence view point, and when the light rays penetrate through the display end, the light rays are displayed on the display end. Each light ray and each layer of screen form an intersection point, the brightness and color information corresponding to the intersection points formed by each light ray on the screen are mutually overlapped in the direction corresponding to the light ray, so that each light ray can reconstruct the brightness and color information of one pixel, and the brightness and color information of the pixel can be reconstructed in a convergence viewpoint. The light rays can reconstruct the brightness and color information of a two-dimensional image corresponding to a single viewpoint, and the resolution of the viewed image is consistent with the resolution of a multi-layer screen, so that the brightness and color information reconstructed on the convergence viewpoint is consistent with the sub-image information corresponding to the convergence viewpoint.

Description

technical field [0001] The invention relates to naked-eye three-dimensional display technology, in particular to a naked-eye three-dimensional display method based on multi-viewpoint reconstruction. Background technique [0002] The traditional 3D display technology mainly uses binocular parallax characteristics and visual persistence effect to enable human eyes to obtain 3D images. However, these display technologies display the object on the display screen, and the position is the position of the object perceived by the monocular adjustment on the two-dimensional plane, while the position of the object focused by the binocular convergence is the three-dimensional object in space, also That is to say, for the human eye, the refractive adjustment and visual convergence of the eyes do not automatically occur simultaneously, there is a direct correlation between them, given any degree of refractive adjustment, it will correspond to a visual convergence degrees, and vice versa...
